0 0 <br /> Sump penetrations The Dualoy sump penetration fitting(Fig.9-1)provides a simple means of penetrating <br /> multi-sided fiberglass tank risers or sumps in contained piping systems.The fitting is <br /> typically mounted through a sump wall.Ported reducing closures(Fig.9-3)may be used <br /> inside the sump to isolate the annular space between the primary and the containment <br /> pipe and to provide a monitoring port.Altematively,the sump fitting is available with a <br /> factory-installed monitoring port(Fig.9-6). <br /> Tank riser <br /> Figs.9-1,2.The Dualoy sump fitting Sand 1 Inch around <br /> (left)provides a simple means of `t-Inch hole <br /> penetrating fiberglass tank risers <br /> (right)or sumps in contained piping i 4 <br /> systems. Remove burrs <br /> around hole <br /> Before installing the primary <br /> • Use a hole saw to cut a 4-inch hole in the sump wall as low as possible to provide <br /> maximum slope into the sump. <br /> • Remove any burrs from the edge of the hole. <br /> • Check hole size by dry fitting the fitting from the inside. <br /> • Using a disc grinder,abrade about 1 inch around the hole to provide a rough <br /> bonding surface. <br /> • Mix Ameron PSX•20 adhesive following the instructions included in the kit.Apply <br /> an even layer of adhesive to <br /> • The edge of the hole and around the hole,on both the inner and outer wall. <br /> • The bonding surface of the fitting flange and flange ring. <br /> • Install the fitting in the proper orientation. <br /> • Make up the nut from the outside and check around the edge of the flange on the <br /> inside and the flange ring on the outside to verify the presence of an adhesive <br /> bead.If a bead is not visible all the way around,remove and restart applying more <br /> adhesive.Tighten with a wrench or by hand. <br /> • Do not move the fitting until the adhesive has cured.Follow the cure time recom- <br /> mendations on the adhesive instruction sheet. <br /> After installing the primary <br /> Most specifications will call for isolating the annular containment space from the sump. <br /> This may be accomplished using 3 x 2 inch containment closure pieces as shown in Fig. <br /> 9-3 or by using a sump <br /> fitting that has been <br /> provided at the factory <br /> Byothers Riser with a bushing in the <br /> Fig.9-3.A ported reducing closure annulus between the <br /> isolates the annular space between ___ _ _ sump fitting itself and a <br /> the primary and the containment primary pipe sleeve <br /> pipe and provides a monitoring port I - - - coupling as shown in <br /> inside the sump.
